我在mysql中的所有原始查询都需要转换为laravel 5.4查询生成器：

SELECT MONTH(calendar.datefield) AS Bulan, calendar.datefield AS Tanggal, IFNULL(SUM(dbk.jumlah),0) AS Jumlah 
FROM detail_brg_keluar AS dbk 
INNER JOIN penjualan AS pen ON pen.id = dbk.id_brg_keluar 
RIGHT JOIN calendar ON (DATE(pen.tgl_keluar) = calendar.datefield)
WHERE 
(calendar.datefield BETWEEN 
 (SELECT MIN(DATE(tgl_keluar)) FROM penjualan AS p
    INNER JOIN detail_brg_keluar AS detail ON p.id = detail.id_brg_keluar 
    WHERE detail.id_produk = 818002) 
 AND 
 (SELECT MAX(DATE(tgl_keluar)) FROM penjualan AS pe
    INNER JOIN detail_brg_keluar AS det ON pe.id = det.id_brg_keluar
    WHERE det.id_produk = 818002))
AND (dbk.id_produk = 818002 OR dbk.id_produk IS NULL)
GROUP BY MONTH(calendar.datefield)
ORDER BY calendar.datefield ASC

这是我的laravel代码，代码错误-_-

$proT = DB::table('detail_brg_keluar AS dbk')
    ->select( DB::raw('MONTH(calendar.datefield) AS Bulan, calendar.datefield AS Tanggal, IFNULL(SUM(dbk.jumlah),0) AS Jumlah '))
    ->join('penjualan AS pen', 'pen.id', '=', 'dbk.id_brg_keluar')
    ->join('calendar', DB::raw('DATE(pen.tgl_keluar)'), '=', 'calendar.datefield')
    ->whereBetween('calendar.datefield', [$from[0]->tanggalAwal, $to[0]->tanggalAkhir])
    ->where(DB::raw('dbk.id_produk = 818002 OR dbk.id_produk IS NULL'))
    ->groupBy(DB::raw('MONTH(calendar.datefield)'))
    ->orderBy(DB::raw('calendar.datefield', 'ASC'))
    ->get();

代码从和到：

$from = DB::table('penjualan AS p')
    ->select(DB::raw('MIN(DATE(tgl_keluar)) AS tanggalAwal'))
    ->join('detail_brg_keluar AS detail', 'p.id', '=', 'detail.id_brg_keluar')
    ->where('detail.id_produk', $id)
    ->get();

$to = DB::table('penjualan AS p')
    ->select(DB::raw('MAX(DATE(tgl_keluar)) AS tanggalAkhir'))
    ->join('detail_brg_keluar AS detail', 'p.id', '=', 'detail.id_brg_keluar')
    ->where('detail.id_produk', $id)
    ->get();

我不知道了？
全部thx
